Watts 547101 3/8 Inch Brass Ball Valve 600 Psi Full Port

Product Description

The WATTS 547101 is a 2-piece, full port brass ball valve designed for controlling flow in commercial and industrial piping systems. Sized at 3/8 inch IPS, it carries a pressure rating of 600 psi and handles a full range of liquids and gases, including water, oil, and gas. The valve features a bottom-loaded, blowout-proof stem for added safety under pressure, a virgin PTFE seat for reliable sealing, and a chrome-plated brass ball for corrosion resistance. An adjustable stem packing gland and stem packing nut allow field adjustment of the stem seal. A steel lever handle is included for quarter-turn operation. Licensed plumbers and pipefitters are the primary installers of this valve in commercial and industrial settings.

This valve is suited for commercial and industrial fluid and gas control applications where a compact, reliable shutoff is required. The full port design minimizes flow restriction, making it appropriate for systems where pressure drop across the valve must be kept low. Typical installation scenarios include plumbing supply lines, HVAC hydronic systems, compressed gas distribution, and light oil service lines. The 3/8 inch IPS thread size fits standard pipe installations in both new construction and retrofit work.

Key Features

• Full port design minimizes pressure drop across the valve
• Bottom-loaded, blowout-proof stem provides a secondary safety barrier under system pressure
• Virgin PTFE seat delivers long-term leak-free sealing with a wide range of media
• Chrome-plated brass ball resists corrosion and reduces friction during operation
• Adjustable stem packing gland and nut allow field servicing of stem seal without valve removal
• NSF approved construction for use in applicable potable water and commercial applications

Compatibility

Designed as an OEM-style replacement or new-installation ball valve for 3/8 inch IPS threaded pipe systems handling water, oil, or gas in commercial and industrial environments.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing codes and IFGC requirements when used on gas service. Shut off system pressure and drain the line before removing any existing valve or making connections. Apply thread sealant or PTFE tape to male threads per the applicable code and media type. Do not over-tighten the lever handle against the stops, as this can damage the seat or stem packing.
